This improved tool is employed for removing a clip I by means of which a, handle 2 is held upon a shaft 3. This handle may be the handle by means of which a door of an automobile is opened and closed or may be the handle by means of which the glass for a'door or window of an automobile is shiftedv to open and closed positions. The shank 4 of the handle is formed with a socket 5 into which the shaft ts and side portions of the shank are formed with openings 5 which register with a groove 'I formed circumferentially of the shaft, and when the clip I is applied its arms pass through the side openings E and enter the groove 1. Therefore the handle will be firmly held to the shaft and when the handle is turned the shaft will be rotated and the door latch released or the glass moved to opened or closed position accordingly to the direction-in which the shaft is turned. Interengaging teeth 8 and 9 of the shaft and the handle causes the shaft to turn with the handle. When the handle is in place upon the shaft it is quite close to the door or sidewall of the automobile and difficulty has been experienced in withdrawing the clip when the handle is to be removed. At the present time it is customary for workman at a service station to use tools resembling a crochet hook and an ice pick for removing the clips but such tools are not satisfactory as the clips, when dislodged, are liable to fly off and become lost or strike the workmans eye and cause injury to his eye.

The improved tool constituting the subject matter of this invention may be used without danger of injury to the workman or loss of the clip. This tool has a frame I9 having arms at its sides formed with inwardly projecting fingers II at their lower ends. A plate of thin metal I2 which is secured by a suitable 'number of screws I3 forms a rear wall for a pocket I4 dened by the inverted U-shaped frame and this rear wall I2 is formed midway the width of its lower end with a recess I5 from opposite sides of which project ends of the fingers II. A hollow handle I6 of tubular formation projects upwardly from the frame I9 to which its lower portion is welded in straddling relation thereto, and at its upper end the handle is closed by a plug I1 held in place by screws I8. A rack'bar I9 is slidable longitudinally through the rear arm or fork 20 of the handle and at its upper end the rack bar is formed with a head 2l which is of such diameter that it may move through the handle. A spring 22 which is held in the handle by the plug I'I bears against the head 2| and yieldably holds the rack bar in the lowered position with its lower end abutting the stop 23 at the lower end of the rear fork 20; Bars 25 project forwardly from opposite ksides of the handle just above the frame I9 and form a housing 26 closed by a front wall or plate 21. A shaft 28 is rotatably mounted transversely through the housing 26 and is held against longitudinal displacement by a collar 29 which is held to the shaft by a screw 30. At its other end the shaft is formed with a head 3l bored to form a socket 32 and into this socket is screwed the threaded lower end of a lever 33. When this lever is grasped and swung downwardly the shaft will be turned and since this shaft carries a gear 34 meshing with the rack bar I9, the rack bar will be shifted upwardly and the spring 22 compressed. When the lever is released the spring expands and returns the rack bar in its original position. The lower end of the rack bar is exposed in the upper portion of the pocket I4 and is formed with a lug 34' which engages and operates clip engaging means 35 in the pocket I4.

The clip-engaging means 35 has a casing formed of front and rear plates 35 and 31 held in spaced relation to each other by side strips 38 which are secured between side edge portions of the plates by screws 39. Recesses 45 and 4Il are formed in lower portions of the plates or walls 35 and 31 and the plate 3l has its upper portion formed with a recess 42 leading from its upper end. Arms 43 extendfrom upper ends of the strips 38 with their ends terminating at opposite sides of recess 42 and at their lower ends the strips 38 are'provided with extensions or arms 44 having end portions of reduced thickness to provide lips 45 having their lower ends bevelled to sharp edges. At opposite sides of the lower end of the recess 4I the plate 31 is bevelled as shown at 43 to form sharp edges which cooperate with the bevelled surfaces of the lips 45 and form guides for directing the clip-engaging member into position between the handie 2 and the surface of the door. Upper edges 41 of the arms 44 extend at an incline and are iiush with lower edges of recesses 48 formed in the side strips 38 near lower ends thereof.

Within the casing 35 is a block 49 which is slidable vertically or longitudinally of the casing and has a shank 5D which is disposed between ends of the arms 43 and is formed with an opening 5I into which its the lug 34 of the rack bar I9. When the rack block 49 will be moved with itv to a raised position and when the spring 22 shifts the rack bar downwardly the block will be returned to its normal position. Jaws 52 fit within the casing 35 under the block 49 and these jaws have upstanding Shanks or stems 53 terminating in. circular head 54 which t into circular sockets 55 formed in the block 49 and mount the jaws for tilting movement towards and away fro-m the recesses or seats 48. When the device is applied to a handle 2 in straddling relation to the shank 4 of the handle and the lever 33 moved to shift the rack bar upwardly the jaws will be shifted towards each other by cam action between the tapered lugs 59 of the jaws and the sloping upper edges of' the recesses 48 and the teeth 51 of the jaws brought into gripping engagement with the clip from opposite sides thereof as shown in Figure 8. Continued upward movement lof the block and thev jaws will cause thejaws to move upwardly between the side strips 38 and-Withdraw the clip from the handle and the shaft and the handle will be released from the shaft for removal therefrom. The doors of automobiles do not lall have the same size handles and some have clips of different shapes. Therefore there have been shown in Figures l2 through 17 jaws having clip-engaging inner side edges of different shape from the jaws shown in Figures 4 through 9. A specific description of the jaws shown in Figures 12 through 17 is not necessaryas they differ from the jaws of Figures 4 through v9 only in the vshape bar is shifted upwardly the.

of their inner side edges. When the lever 33 is released and the spring 22 returns the rack bar and the block to the initial or lowered position the jaws move downwardly with the block and since the jaws are urged apart by a plunger 5S forced downwardly by a spring 59 the jaws will be moved apart and into the recesses 48. Therefore the clip will be released and will drop into the hand of a workman held under the tool. If it is found that the jaws of a clip engaging member 35 do not ilt the clip and handle to be removed it is merely necessary to remove the casing 35 and insert one having jaws of the proper size and shape. When the casing is fitted into the pocket l 9 and the lug 34 engaged in the opening 5 l, the casing must be prevented from slipping out of the pocket during use of the tool. In order to do so there has been provided a clamp 60 carried by short shafts 6i which are rotatably mounted through bearings 62 at opposite sides of the frame i9. Inner ends of the shafts are formed with heads 63 constituting cams and when the clamp is in its raised position the |casing 35 may be slipped into the pocket Il?. with its side edge portions moving under the flat faces of the cams. After the casing is in place the clamp is swung downwardly and the cams move into gripping engagement with the casing. When the tool is to be applied to a door handle the clamp is swung upwardly and the tool slid downwardly into straddling engagement with the shank of the door handle. The clamp is then swung downwardly to r-mly hold the casing in the frame of the tool and the door handle 2 engages in the notch 64 formed in the bridge of the clamp so that the tool will be held close against the door and prevented from shifting upwardly by wedging action of the handle 2 in the notch 59. When the clamp Si is swung upwardly out of engagement with the.door handle the tool may be easily moved upwardly out of engagement with the door handle and carry the clip with it.

In Figures 18 through 24 there has been shown a modiiled form of clip removing tool. embodiment of the invention the frame $4 has side bars 55 corresponding to the side bars or arms of the frame I9 and at the upper ends of the side bars there is formed a handle 53 which is or inverted U-shape and takes the place of the rigid handle I9. The casing It9, carrying the sliding block 'lli and the jaws Il which are pivoted to the block, nts into the frame 64 between the side bars of the frame and since the action of the jaws during vertical movement of the brook is the same as previously described it is not necessary to specically describe the same. provided between ends of the inwardly projecting fingers at upper ends of the side bars of the casing for allowing outward movement of the shank of the block 19 as the block moves upwardly and this space registers with the passage T2 of the main frame. A rack 13 is formed longitudinally of the block and its shank and with this rack meshes a gear 14 carried by a shaft 15. The shaft 75 is rotatably mounted through a housing 16 carried by and projecting forwardly from a. plate ll which is provided at its upper ends with bearings 66 through which pins 6'! are passed to pivotally mount the plate 'l1 on the frame 64 and the plate rests against the outer face of the casing 69 and side bars 65 of the main frame and is rmly secured by hooks 'I8 extending from ends In this A space is of the arms of the clamp 19. This clamp has its arms pivotally mounted by pins which pass through bearings 8| at opposite side edges of the plate Tl and when the clamp is swung downwardly the hooks 18 engage the pins or lugs 92 at sides of the main frame and firmly secure the plate to the main frame. Springs `83 surround the shaft l5 within the housing 16 and when the shaft is rotated to shift the block upwardly by applying downward pressure to the handle all of the shaft the springs which are anchored to the shaft and end walls of the housing will be tightened and serve to impart reverse rotation to the shaft and lower the block and the jaw when the handle is released. In both embodiments of the invention illustrated the jaws will grip the clip and withdraw it from the door handle when the block is shifted upwardly and when the clamp is swung downwardly to its lowered position it serves to firmly hold the clip-engaging means in place within the main frame as well as serving to engage the door handle and holding the tool anchored to the door handle during removal of the clip.

Having thus described the invention, what is claimed is:

In Ia tool for removing a handle-securing clim a frame embodying a pair of spaced arms, a clipengaging means operatively connected to said frame, said clip-engaging means comprising a pair or spaced side strips secured to said arms, there being an opposed recess in the inner face of each of said side strips, said recesses being arranged adjacent the lower ends of said side strips and having a substantially V-shape, the recesses extending inwardly from the inner longitudinal edges of said side strips, said recesses being arranged in alignment with each other, a plate arranged on each side of said frame and secured to said side strips, a block slidably positioned between said side strips, a shank projecting from one end of said block, there being a pair of spaced circular sockets in the other end of said block,A a circular head seated in each of said sockets, a stem secured to each of said heads, and a jaw secured to each of said stems, said jaws being mounted for movement toward and away from each other, each Iof said jaws being provided with a V-shaped lug at its lower end for cooperating with said recess to produce movement of said jaws toward and away from each other, means operatively connected to said jaws for normally urging the latter apart, `and V-shaped teeth on the inner faces 0f said jaws for gripping said clips therebetween.
